The unit was raised in Dublin in December 1854 under the title of
Dublin City Artillery Militia. The first commanding officer (CO), appointed on 17 November 1854, was
Lieutenant-Colonel-Commandant the Hon. Robert French Handcock, son of
Lord Castlemaine and a
Half-pay RA
Captain. At first the headquarters (HQ) was at
Lucan, Dublin, transferring to Dublin City in 1861. Training of the Irish Militia was suspended in 1866. When training resumed in 1871 the acting CO following Handcock's death was
Major Francis de Burgh, who was promoted to Lt-Col on 17 December that year. Longstanding officers of the unit continued to be promoted to the command: Lt-Col W.J.N. Magill on 31 August 1878, Lt-Col W.C. Dickenson on 18 November 1896, and Lt-Col William L. Smythe on 14 February 1903. In 1898 the unit was reorganised, with three companies becoming field artillery batteries armed with
12-pounder RBL guns, the other two companies becoming 'position artillery' (semi-mobile heavy field artillery) armed with
40-pounder RBL guns. From 1902 most units of the Militia artillery formally became part of the
Royal Garrison Artillery, the Dublin unit taking the title of '
Dublin City RGA (M). ==Embodiments==
